What is reference? explain​

Reference is a link between objects where an object designates or acts as a means to link to an object. This relationship refers to the first object in this relationship.

Explanation:

References can take various forms including a thought, an audible sensory perception (onomatopoeia), visual perception (text), olfactory or tactile, emotional condition, relationship with others,  space-time coordination, an object or energy projection, a symbolic or alphanumerical one. Some methods, such as cryptography, are used which deliberately hide the reference from certain viewers.

References are found in many areas and the term embraces meaning in the context of human activity and knowledge.

Usually, a name is a phrase or expression, or a symbolic image. Its reference could be an abstract concept, a material object, a person, or an event.

Reference is a relationship between objects in which one object designates, or acts as a means by which to connect to or link to, another object. The first object in this relation is said to refer to the second object. It is called a name for the second object.
